16. The logic supply can be any value VL – VLR = +1.71 to +3.465 volts as long as VLR ≥ V2- and VL ≤ 3.465 V.
17. The differential voltage reference magnitude is constrained by the V1+ or V1- supply magnitude.

WARNING:
Recommended Operating Conditions indicate limits to which the device is functionally operational. Abso-
lute Maximum Ratings indicate limits beyond which permanent damage to the device may occur. The
Absolute Maximum Ratings are stress ratings only and the device should not be operated at these limits.
Operation at conditions beyond the Recommended Operating Conditions may affect device reliability, and
functional operation beyond Recommended Operating Conditions is not implied. Performance specifica-
tions are intended for the conditions specified for each table in the Characteristics and Specifications sec-
tion.
